I smoked for almost 50 years, albeit sparsely for the early years, and no matter how much I may have wished I didn't smoke, I only had to seriously think about it, and I smoked more!
A couple of years of too many stressful situations had seen my daily use go to an average of 36, and my eyes were suffering, not to mention annoying catarrh & sinus troubles.
It happened just about by accident: I had a disposable e-cig that I hardly used (kept for odd times in places where I couldn't smoke), and I decided to try and use it for most of a day to see if eyes felt better.
I was surprised at bedtime to find I'd smoked 10 less, and next day my eyes were a little better, so I repeated the experiment and found that without trying I'd only smoked half my usual amount.
I was fascinated and rather bemused by it, so I bought some more disposables - by the end of a week I was smoking around 6 per day, so got my first starter kit of e-cigs (Smart Cigs). Another week and I was smoking one each day. Fair enough, it had begun to need more concentration on not smoking, but it wasn't causing me major effort or distress, much to my surprise.
I went on to try V2, and then GreenSmoke, and I have my favourite cartridges with each. I began with 2.4 strength, then mixed in 1.8, and last week got a mix of 1.2 and 0.6. I tend to use the 0.6 in one, 1.2 in another, and mostly use the lower strength mostly at night when I tended to smoke more real cigarettes.
I told no-one about it, and surprisingly, no-one noticed that there was no smell of cigarettes in the house or on me! I decided that not saying anything meant that I couldn't be scrutinised, asked questions, or put under any pressure if I caved in and smoked a cigarette, or gave up on the e-cigs. I hadn't given myself any pressure over it and decided not to give myself a hard time if I filed or faltered. The very fact that I had a secret that was fascinating me by it's effectiveness made me all the more happy to carry on and test my own capabilities unhindered.
It was only when my husband told me off for coughing and sternly told me I should stop smoking that I started laughing - it had been two weeks since I'd smoked by then, and seeing his angry response to my amusement, I had to tell him.
He was very suspicious about it all, and only agreed that I'd done well after I explained all about electronic cigarettes.
I asked him not to ask questions as to how I'm doing, and to just let me get on with it. The same applied to both our sons when they visited, and thankfully, they haven't.
I was very happy to tell them recently that it had been a month, and all were really pleased.
Somehow, I'm taking the stance that having been a smoker for such a long time, I'm reluctant to say that I'm an ex-smoker, but happy to regard myself as 'I don't smoke'. I keep an open mind ...after all, I'm only human

I fully intend to carry on this way and perhaps get to using 0.6 only eventually - for now, I'm happy ...it was a 'happy accident'!
